What runners say

Exactly what i was looking for!

Hideki, Japan, I run 20 - 40km per week, I run primarily to build endurance

During the winter season, i always have a problem of my hands and my wrists getting too cold while running. It gets too cold to an extent that it hurts. I therefore need a long sleeve to protect my arm and my hands. Yet when i go for a run, my body gets warm and i sweat. So i prefer to wear something that has good insulation and nothing that is too warm. I have been struggling to find the right running gear for this contradictory situation, and this Clima-Shirt was exactly what i was looking for! it covers my hand and my arms, yet at the same time with the good insulation material, it keeps my body cool if it heats too much. thank you ON, and i definitely need to buy an extra pair in the near future.
